Does it work on heavy-duty vehicles?

All of our Innova diagnostic tools will work on heavy duty vehicles as long as they are OBD2 compliant. You can check whether the vehicle is OBD2 compliant by checking the emissions label on the roof of the hood, or near the radiator. 

No. The USB cable is not included for this tool. 

The PC-Link software will allow you  to check for available updates or upgrades for your scan tool/code reader. The software will also allow you to connect the scan tool/code reader to a PC and transfer the information retrieved from your vehicle’s computer.

No, unfortunately recorded live data cannot be transferred onto our online software. 

You can download the Owner’s Manual from the Innova website (www.innova.com). Click on the "Support" Tab, and choose "Manuals and Software". 

The flashing I/M MONITOR icons represent systems that are still being tested by your vehicle for any possible faults. Those icons will go solid once the testing is complete, which you do by completing a drive cycle procedure for that specific vehicle.  

Yes, the tools are still able to establish a successful connection with a vehicle that cannot crank up and start. If your vehicle has no power however, our tool will not be able to establish a connection to the vehicle since our tools require power from the vehicle to successfully connect.

We always recommend connecting the 3040e to your vehicle first, before turning on the ignition or starting the vehicle. So long as this procedure is followed, you can use the Code Reader on the vehicle while it is running. IMPORTANT: If it is necessary to drive the vehicle while observing the Code Reader's display (such as when performing a Drive Cycle), ALWAYS have a second person help you. One person should drive while the second person observes the Code Reader's display.

The tool is powered by the vehicle's accessory fuses. If the tool does not power on when you connect it to a vehicle, most likely, there is an accessory fuse blown. Replace that blown fuse to get the tool to successfully power on and connect. 

To register your tool, simply download the RepairSolutions software from the Download Manual/Software tab above. Once the installation is complete, connect your tool with a USB cable and follow the intructions on your computer once the tool has been connected. 

Yes, the 3040e will save the last 3 vehicles scanned.

You will have to scan another vehicle  to override a previous vehicle. There is no alternate way to delete a previous vehicle on the tool.

The 3040e will retrieve ABS codes, on most 1996 and newer Domestic vehicles. However, it will not retrieve SRS codes. Please refer to our compatibility chart for more information.

No. Innova’s code readers/scan tools are designed to retrieve information that is stored in your vehicle’s computer. It is not possible for these tools to damage your vehicle’s electronic system.
